create a mapping variable name $$max_bound of integer data type and aggregation type max
now in expression variable
seq v seq+1
o_seq o seq
v_temp v v_temp+1
curr_val v IIF(v_temp=1,setmaxvariable($$max_bound,$$max_bound+2),0)
o_map_val o setvariable($$max_bound,NULL)
now come to filter transformation
and write condition as
(seq<=$$max_bound)AND(seq>$$max_bound-2)
Thanks

Answer / naveen
You are right , this can be achieved only with the help of
the mapping variable. and also a filter transformation
1) create a mapping variable and assign a default value 0
2)during the first run , i hope ur source must have an seq
num in it, if not use the seq gen and have unique sorted
record.
3)in a n expression , just have v_max_filter =
@@map_variable + 2 and v_min_filter = @@map_variable - 2
4) in the filter transformation , put the filter on the
seq_column <= v_filter and seq_column >= v_min_filter
5) enjoy a coffe, this will run
